摘　　要：通过添加硅酸盐对水性环氧树脂乳液进行改性,制备了石质文物表面防护剂。以山西大同云冈石窟的砂岩为保护对象,测定了该表面防护剂的防水性、耐水性、接触角、耐紫外线、安定性和耐盐性等性能指标。结果表明,硅酸盐改性水性环氧树脂乳液对石质文物的表面保护具有良好的效果。Silicate was used to enhance the property of waterborne epoxy resin emulsion and a kind of surface repellent for stone historical relic was prepared. The main properties of the surface repellent, such as water resistance and salt resistance, freeze-thaw resistance and absorption to ultraviolet light, were improved in comparison with silicate free waterborne epoxy resin emulsion by using the sandstone in Shangxi Datong Yungang Grotto as a sample, It is excellent environmental paint for preservation of stone historical relic.
